摘要
提出一种基于博弈论的耐撞性多目标优化设计方法,用非合作博弈处理多个目标之间的冲突,以达到纳什均衡状态的解作为最优解。并以某新车型为例,应用均匀设计和移动最小二乘法构建了代理模型,进行了面向US-NCAP法规的结构耐撞性优化设计,取得了比传统的线性加权法更好的优化效果。
A new method for vehicle crashworthiness multi-objective optimization is proposed based on game theory. Non-cooperative game theory is used to deal with the conflict among multiple objectives, and the Nash equilibrium solution is taken as the optimum one. Taking a new car model as an example, the uniform design and the moving least square method are applied to setting up a meta-model, and aiming at the requirements of US-NCAP regulation, a structure crashworthiness optimization is linear weighted method. performed, achieving a better effect than that by traditional
